	Yes, I think I posted on this very topic recently. :)  Having thought
it over some more, and at the risk of damaging Asami-san's sanity, I
would suggest that we have:

PERL_RELEASE=perl5
PERL_MAJOR=005
PERL_PATCH=02

.if <this is 3.0>
PERL_DIRECTORY=/usr/bin
.else
PERL_DIRECTORY=/usr/local/bin
.endif

PERL=${PERL_DIRECTORY}/${PERL_RELEASE}
PERL_MEDIUM=${PERL_DIRECTORY}/${PERL_RELEASE}.${PERL_MAJOR}
PERL_LONG=${PERL_DIRECTORY}/${PERL_RELEASE}.${PERL_MAJOR}.${PERL_PATCH}

If we're going to make the change, my vote is to make it in such a way
that it will be easy to change with a few keystrokes in the future.
